CVE-2026-72731Network attack vector

Database disclosure via recursive SQL parameter interpolation

Published Aug 10, 2026 · Updated Aug 10, 2026

SQL injection in Discourse Data Explorer allows remote authenticated users with query access to read any database table. DataExplorer.run_query and the SQL action workflow recursively reprocessed substituted values and honored parameter declarations inside SQL comments, letting crafted values escape the intended query. Access to a parameterized shared query is sufficient; execution is read-only, so the flaw exposes data but does not modify it.
